You village is in danger. The beach is taken by Vikings and they are jump out right now.
It’s a strategy or match-3 game? At first you build several towers to help you in the struggle and then, in the fight, you click on colored wizards. When they disappear they shoot a magic shot. After every day and several waves you get some money for a bit expensive upgrades and continue further. Click Battle is long game maybe too long but still fun.
